COA to NAS behind proxy

[Sachin Yadav]

Hi,
I am trying it kick out user once monthly data limited is reached while account-update packet is received. My setup is -
Freeradius ====== internet =========== ISP ===== modem ===== router(running chillispot)
At freeradius i get public IP assigned to modem from ISP and now no matter what IP i try to send COA packet it fails. I have following entry -
Client.confclient 0.0.0.0/0 {        secret      = xxxxx         nastype     = other         coa_server = localhost-coa}
originate-coahome_server localhost-coa { type = coa ipaddr = localhost
 port = 3799 secret = testing1234
# rest all is default......

default (in accounting section)
 update control    {        Tmp-Integer-0 := "%{sql:#query}"        Tmp-Integer-1 := #query}if ("%{control:Tmp-Integer-0}" > "%{control:Tmp-Integer-1}") {
 update disconnect {     User-Name = "%{request:User-Name}"    Acct-Session-Id = "%{Acct-Session-Id}"     NAS-IP-Address = "%{NAS-IP-Address}"}}


Logs shows -
